    Hello,

    To store last communication time, you need to create a new channel, and develop a formula that stores the time in that channel.

    Keeping last good value can be done by the formula.

    Hello,

    In TCP communication, a connection brakes silently sometimes. If a client cannot poll a server, it must reconnect if there is no reply or connection is idle for a period.

    In a formula you can check values of other channels. So you should add a function to the Scripts table, and then use that function in a channel formula.

    I will not write the formula for you, because writing complex formulas is a paid service, but I can help to solve the related questions.

    Dear Arya,
    I suggest to add a new archive in the Archives table and in the Server settings.
    This archive should not be default. Set archive mask for channels that will be written in the archive.

    Since SCADA use port 80 and the embedded iframe use port 8080.

    Yes. It’s called origin. You should check the error details in the browser console and network tools.

    Also you can send a request according to the instructions and analyze it by Wireshark.

    Contact the provider’s technical support and ask for an example of content type and body of the POST request. Then use it in the device properties.

    Hi,

    If an external web page is open in a frame, we don’t have access to its title, because of browser security. Therefore URL is displayed.

    Try to configure DrvHttpNotif according to the provider requirements.
    CURLOPT_POSTFIELDS probably should be specified on the request body.

    Yes. When command is send by Automatic Control module, the phone number is taken from the address book, and the text can contain variables.
